LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 791,621, dated June 6, 1905. Application led January 18,1905. Serial No. 241,659.

Be it known that I, GEORGE Hooks, a citizenof the United States, residing at Institute, in the county of Door and State of Wisconsin,v

have invented a new and useful Lubricator, of which the following is a specification.

This invention relates to lubricators, and has for its object to provide an improved device of this character which is particularly designed for application to hubs of wheels, pulleys, and similar rotatable members.

Further objects of the invention are to facilitate the attachment of the device, to obtain a direct feed of the lubricant, and to enable the convenient filling of the oil-reservoir.

With these and other objects in view the present invention consists in the combination and arrangement of parts, as will b`e hereinafter more fully described, shown in the accompanyin drawings, and particularly pointed out 1n the appended claims.

In the accompanying drawings, Figure 1 is a fragmentary elevation of the inner end of a vehicle-wheel with parts broken away to illustrate the construction of the present lubricator. Fig. 2 is a detail perspective view of the device detached.

Like characters of reference designate cor- -responding parts in both figures of the drawings.

While the present device is capable of application to various kinds of wheels and theinner end of the hub.

outer side of the adjacent terminal of the band being provided with an opening 3, registering with the open outer end of the reservoir. The inner end of the sleeve is open for ried by' the opposite end of the band, which v latter is capable of lapping the opposite end thereof in order that the cylindrical plug 4 may enter into the sleeve 2 through its outer open end. By preference the body of the plug 4 is of rubber and is connected to the spring by means of a threaded fastening 5, piercing the band from its outer side, whereby the plug e tends radially inward from the band.

In applying the lubricator to a wheel, as shown in Eig. 1 of the drawings, wherein the reference character 6 indicates the inner end of the hub of the wheel, a substantially radial opening 7 is formed through the hub, so as to communicate with the spindle-opening thereof, and to prevent saturation of the hub by the oil a metallic tube or sleeve 8 is snugly tted into the opening to form a lining therefor and is held in place by means of fastenings 9, passed through flanges or ears 10, lying against the outer periphery of the hub, said ears preferably being let in iiush with the surface of the hub. After the opening has been produced in the hub the band l is placed Varound the huband the sleeve 2 is inserted into the o ening. The oil is then introduced in-to the s eeve, and then the plug 4 is fitted into the open outer end of the sleeve, the tension ofthe band serving to clamp the entire tire device upon the hub and tending to force the plug inwardly, so as to close the open outer end of the oil-chamber in a very simple and efficient manner. To recharge the reservoir or oil-chamber, the plug is withdrawn without entirely removing the band from the hub, whereupon the reservoir may be filled and the plug then returned to the reservoir. To facilitate the Withdrawal of the plug from the oil reservoir or chamber, the free eX- tremity of the spring-band is deflected or turned outwardly, as at l1, to form a nger- IOO piece, beneath which a iinger or other means may be introduced to pry the plug out of the reservoir.

From the foregoing description it Will be understood that the prese-nt device is in the nature of an attachment and is entirely complete in itself, Wherefore it may be readily attached to a Wheel Without material alteration therein beyond the formation of the opening to receive the reservoir. Moreover, as the tension of the spring-band retains the device in place extraneous fastening means are not essential, and therefore the device may be very quickly applied and removed. As the device is carried entirely by the hub, the Wheel may be removed Without detaching the lubricator, and it is not necessary to 'remove the Wheel when it is desired to recharge the reservoir with oil.

Having fully described the invention, what is claimed is 1. A lubricator comprising an elastic clamping-band having a sleeve upon one end and a plug upon the opposite end of the band and capable of being inserted into the sleeve.

2. A lubricator comprising an elastic band having a tubular open-ended sleeve carried by one end of the band and extending in- Wardly therefrom in a substantially radial direction, and a substantially cylindrical plug extending inwardly in substantial radial relation from the other end of the band and capable of being inserted into the open outer end of the sleeve.

3. The combination with the hub of a Wheel having a substantially radial opening in communication with the bore thereof, of a lubricator comprising a spring-band einbracing the hub and provided upon one end with a sleeve fitting in the opening in the hub and having a plug carried by the opposite end of the band and fitting in the sleeve.

4. A lubricator comprising a spring-band having 'a sleeve at one end thereof, a plug at the other end to iit Within the sleeve, and a threaded fastening piercing the band and the plug to connect the latter to thc band.

In testimony that I claim the foregoing as my own l have hereto aflixedv my signature in the presence of two Witnesses.

GEORGE HOCKS.
